Nationals right-hander Doug Fister dealt with elbow problems early in spring training and then, just when he was over them and getting ready to start the season healthy, he suffered a strained lat muscle in yesterday’s game.

William Ladson of MLB.com reports that Fister will be placed on the disabled list to begin the season, which likely means Taylor Jordan and Tanner Roark will both be in the Nationals’ rotation after competing with each other for the fifth-starter gig previously.

Fister was acquired from the Tigers this offseason in a trade that had many people wondering why Detroit gave him up so cheaply, but his spring was filled with setbacks. He started 32 games last season and logged 209 innings with a 3.67 ERA and 159/44 K/BB ratio.

Nava began the season on a one-year contract with the Angels, during which he slashed .235/.309/.303 through 136 PA in the first half of 2016. He was flipped to the Royals in late August for a player to be named later and saw the remainder of his year go down the drain on an .091 average through 12 PA in Anaheim. After getting the boot from the Angels’ 40-man roster in November, the 33-year-old outfielder elected free agency.

Nava is expected to compete for a bench role on the Phillies’ roster in the spring. As it currently stands, the club’s projected 2017 outfield features Howie Kendrick and Odubel Herrera, with precious little depth behind them. Nava’s bat is underwhelming, but at the very least he offers the Phillies a warm body in left field and a potential platoon partner for one of their younger options, a la Tyler Goeddel or Roman Quinn.

Former Mets catcher Johnny Monell signed a contract with the KT Wiz of the Korea Baseball Organization, per a report by Chris Cotillo of SB Nation. The 30-year-old originally struck a deal with the NC Dinos on Thursday, but the deal appeared to fall through at the last minute, according to Cotillo’s unnamed source.

Monell last surfaced for the Mets during their 2015 run, batting a dismal .167/.231/.208 with two extra bases in 52 PA before the club DFA’d him to clear space for Bartolo Colon. While he’s had difficulty sticking at the major league level, he’s found a higher degree of success in the minor league circuit and holds a career .271 average over a decade of minor league play. He played exclusively in Triple-A Las Vegas during the 2016 season, slashing .276/.336/.470 with 19 home runs and a career-high 75 RBI in 461 PA.

The veteran backstop appears to be the second MLB player to join the KT Wiz roster this offseason, as right-hander Donn Roach also signed with the club last month on a one-year, $850,000 deal.
